摘　　要：目的对比评价丹参中主要活性部位的血管舒张及心肌细胞保护作用,明确各活性部位在心肌保护作用中的主要贡献。方法分别利用大鼠胸主动脉血管环及心肌细胞缺氧再复氧损伤(HRI)模型实验对丹参4个活性部位:总丹参酮部位(DSBW-1)、丹参总酚酸与粗糖蛋白混合部位(DSBW-2)、丹参总酚酸部位(DSBW-3)和丹参粗糖蛋白部位(DSBW-4),进行心肌保护作用研究和评价。结果血管舒张实验结果表明,DSBW-3作用最强,血管舒张百分比为(55.67±3.09)%;心肌细胞保护实验表明,DSBW-1对心肌细胞保护作用最强,与模型组相比,对HRI细胞具有显著的保护作用。结论丹参中丹参酮和丹参酚酸类物质均有一定的心肌保护作用,但作用途径和贡献不同,推测二者在心肌保护作用中可能具有一定的协同作用。OBJECTIVE To evaluate the myocardial protective effect of the major active extracts from Salvia miltiorrhiza Bunge（SM）, and clarify their different contributions in myocardial protection.METHODS Using rat aortic rings and cardiomyocyte hypoxia-reoxygenation injury（HRI）model, experiments of SM about four active fractions, include the total tanshinones, the mixture of total salvianolic acids and glycoproteins, the total salvianolic acides, and the glycoproteins were evaluated on myocardial protection.RESULTS The vasodilator experimental results showed that the total salvianolic acides had the strongest effect and the percentage of vasodilatation was （55.67±3.09）%. The experimental of myocardial cells protection showed that the total tanshinones had the strongest protective effect on myocardial cells, and compared with model group, it had significant protective effect on HRI cells.CONCLUSION The tanshinones and salvianolic acids in SM have myocardial protective effect, but they have different pathways and contributions, which speculates that they may have a synergistic effect in myocardial protection.
